Present: Alexei, Flemming, Jim, Yuri, Gene, and myself
== Hardware
— Smoking oil from a pump in tunnel triggered smoke alarms
— STAR magnet tripped around the same
— drift velocity has been essentially stabilized (5.55 cm/us)
— temperature is stable in TPC air blower
— some mild humidity issues (perhaps brought in by high winds)
— anode trips are somewhat better lately
— will ask shift crew to include information about TPC trips when logging beam loss or beam dump
== Electronics
— still the usual losses and repairs of RDOs and FEEs (usual 15% dead on average)
— one TPX RDO lost over the past week (2 total now that cannot be recovered without removing the pole tip)
— 3 HV sections are running with lower voltage
== Software
— continuing work on for hit errors for DAQ5000
== AOB
— TPC meetings have been put back into STAR Drupal Calendar for next few months
Best Regards,
Richard
